Cairn Terriers are small dogs. They typically weigh between 13 to 18 pounds and stand about 9 to 13 inches tall at the shoulder. Their compact size makes them suitable for various living situations.

Cairn Terriers are known for their confident, playful, and intelligent nature. They are spirited and energetic, often displaying a feisty attitude. They tend to be good with children and can get along well with other pets if properly socialized. Their strong prey drive means they may chase after smaller animals, so consistent training is important.

The Cairn Terrier has a double coat with a harsh, wiry outer layer and a softer undercoat. Their coats come in various colors, including brindle, gray, black, red, sand, and cream. Regular grooming is necessary to maintain their coat and prevent matting, with brushing recommended a few times a week.

Cairn Terriers thrive in active households where they receive plenty of attention and exercise. They adapt well to various living environments, including apartments, as long as they have access to regular outdoor activities. They do not like to be left alone for long periods, as they value companionship and can become bored or anxious.

Cairn Terriers enjoy a variety of activities, including walks, playtime in the yard, and engaging in games like fetch. They excel in agility and obedience training because of their intelligence and eagerness to please. Providing mental stimulation through interactive toys and puzzle games is also beneficial for their overall well-being.
